Other releasable and reusable fasteners that also do not require the use of a separate tool to operate are also contemplated for example magnets or other hook and loop style materials.

Referring to FIG. 16 a weep path 292 is illustrated for a path for liquid that may enter the sash assembly to be vacated from the fenestration assembly. A path 292 is created by a routed path extending into second intermediate sash member 126. Path 292 includes a first downwardly extending portion 296 that extends from an upper surface 294 that defines a generally horizontal plane when the fenestration assembly is in an in use position in an vertical wall of a structure. Path 292 includes a bottom portion 298 that is a given vertical distance from upper surface 294 in a direction defined by vector 301 which is the same direction as gravity when the fenestration assembly in in an in use position in a vertical wall of a structure. Path 294 includes a portion 300 which extends from bottom portion 298 in a vector direction 306 generally opposite and perpendicular to the slope defined by the slope defined by path portion 296. Path portion 300 is in fluid communication with a portion 302 that has a vertical vector distance from region 294 that is less than the given vertical vector distance of bottom portion 298 from region 294. Path portion 302 has an exit to surface 304 of second intermediate member 126. In operation water that may enter path 292 from region 294 will flow downwardly along path portion 296 and only exit path 292 at surface 304 when the height of water in path 296 from bottom portion 298 along vector 306 is greater than the distance along vector 306 between exit apex portion 308 and bottom portion 298. A certain amount of water will remain within path 292.

Weep path 292 is completely routed in second intermediate sash member 126 and therefore does not requires any further drilling of apertures after the formation of intermediate sash member 126 by process 166. Weep path 292 is closed off in the direction 303 by the inner face of first outer sash member 124.

Referring to FIG. 17 a cross section of the sash assembly 104 and frame assembly 102 illustrate the hidden nature of hinge assembly 310.
